%description
Provides tools for calculating solar geometry, solar radiation on
horizontal and inclined planes, and simulating the performance of various
photovoltaic (PV) systems. Supports daily and intradaily irradiation data,
enabling detailed analysis of grid-connected and water-pumping PV systems,
including shading effects and solar angle calculations.
